Abstract: GIS is used as a platform to collect and analyze the geographic information of the transmission line path selection,and use analytic hierarchy process to quantify and integrate complex geographic information in geographical units.In combination with the characteristics of the transmission line path selection,an improved model of ant colony algorithm search for the path is established.The model uses the heuristic search,integrate the local cost control and the A* algorithm,which makes the path search faster and more accurate.The geographic data is provided by the actual aerial,using the C#2010 and the ArgGis 10.0 to build a transmission line path automatic selection procedures,which verified the validity of the model and the method.

Key words: transmission line paths search, GIS, analytic hierarchy process, ant colony algorithm, A* algorithm
